Here's yet another opinion on DES exportability.

     The  communications on  exporting the  DES  algorithm which  have
appeared on the net recently are ALL correct.   Huh? What did you just
say?  Read on.

     If something not  subject to  ITAR  regulations is in the  public
domain, or "widely  published"  in the US,  any  citizen has a general
license to export that information.  If fact you  may go  overseas and
speak publicly about what  you know, and  that will create information
subject to license  requirements,  qualify it for general license, and
export it.  In other  words, as  an American citizen,  your freedom of
speech does not end at the waters' edge.  (The  country where you give
the  speech might not  like what  you   say, but  that  is a different
issue.)

     However, if you have information subject  to ITAR regulations (no
matter how you got it), you (or your company) can be prosecuted if you
export it  without  State   Department  approval.   See the  "aid  and
comfort" clause in the constitution. Since  some crypto information is
clearly  protected this way, most  company lawyers "take  the easy way
out" and advise the company not to export any crypto software, without
checking to see if it falls under the ITAR rules.

    (Apply standard disclaimers to what follows at least  twice.) Last
time I checked the "opinion" of State was that  the  DES algorithm was
not subject to ITAR rules,  although  certain implementations (usually
in the  form  of chips)  were  protected.   Note  that  any government
employee must be vague here, either he knows all the (classified) uses
of crypto (and where is YOUR need  to know) but  can't tell you, or he
doesn't know and  can't be    more specific.   Therefore the  standard
procedure is  to    request   an  opinion  before    exporting  crypto
implementations, and if you don't get something on  the order of "your
application does not currently appear to fall under ITAR rules..." you
talked to the wrong person (or  you really are trying to  export a 300
MIP DES chip 8^> ).

     If you do ACCIDENTLY export  something subject to ITAR rules, you
probably won't  go to jail.    In  any violation,  your rights to free
speech must be shown to conflict with other constitutional powers, and
the balence must tilt strongly against you before the ITAR regulations
have any  standing.  If you   intentionally violate  the   ITAR  regs,
however you might not have any constitutional protection.

     Let me give   you a realistic  example.  You   buy a Zowie   1000
portable computer  and  take it  with  you to England.  Unbeknownst to
you, the Zowie 1000 is  used in a  test system for Stealth  Bomber ECM
equiptment.  You  violated the   ITAR regulations, but   in the normal
course of events, you won't even know it, because the DoD  is unlikely
to  tell  the Customs  people which  COTS   (commercial off the shelf)
equipment is used on black projects.  In any case  your  violation was
innocent and is probably protected.

     Second case,  an ATE specialist  on  the Stealth project  buys  a
Zowie 1000 for personal use  because he uses it at  work and likes it.
He takes  it  (and some  of his software)  to England on his vacation.
Dumb, and the  security folk at  the plant may  have a  long talk with
him, but if it was innocent probably  no long term repercussions.  The
third  case of course,  is  he  takes it with him  and  sells it  to a
foriegn  agent for $100,000 -- and  twenty years hard labor.  What did
you think the ITAR regulations were for anyway?

     So now you  know  why  all the  weasel words.    If you   take my
(knowingly incoorect) advice (or someone elses) and innocently violate
the ITAR  regs, I'm guilty and  you  are not...   "So  you're going to
Berlin on  your  vacation?  Could you  do   me a favor?   I  have this
package for  my sister,  but the mail takes weeks.   I'll give you ten
bucks for your trouble."  You are only guilty if you think  he's a spy
and do it anyway...  Each case is  different, and an awful lot depends
on intent.

     It would be nice if someone who has  requested and recieved (from
the government, not from a company lawyer) a recent opinion on the DES
algorithm, would post the opinion here.  If no one out in net land has
a recent opinion,  someone should go  ahead and request one.  The most
recent opinion  I have seen was  two companies back,  and   things can
change in either direction.

Disclaimer: Oh boy, do I need one here.  If you  have any intention of
exporting  anything which might  be subject to  ITAR  rules, have your
lawyer check with the State Department and get a written opinion.   If
you decide to create a test case and  take  it  to  the Supreme Court,
I'll be glad to come cheer, but if you expect me to get up  and say it
was all my idea, you didn't read carefully.

Second  Disclaimer: I  didn't ask MITRE,   MITRE's lawyers, or  anyone
elses lawyers  for their opinion of  this message, but if  I  did, I'm
sure that they would waffle at least as well as I did.
